Item 8.01. Other Events.

Phase 2 Clinical Trial of Tazemetostat Update

The Company is conducting a registration-supporting international 150-patient, five-arm phase 2 clinical trial of tazemetostat for the treatment of NHL. Patients in the phase 2 NHL study are stratified into one of five arms:

 

    Germinal center DLBCL, wild-type EZH2,

 

    Germinal center DLBCL, mutant EZH2,

 

    Non-germinal center DLBCL,

 

    Follicular lymphoma, wild-type EZH2, and

 

    Follicular lymphoma, mutant EZH2.

Overall, enrollment in the five-arm phase 2 NHL study is proceeding as expected. Each of these arms will enroll 30 patients subject to an interim futility analysis for each arm. To date, based on preliminary response data, the Company believes that it has surpassed futility in two of the five arms, and it has not yet achieved the necessary events to determine futility or non-futility in the other three arms. Definitive futility analyses will be determined at a later date by an independent data safety monitoring board.

Planned Phase 2 Clinical Trial of Tazemetostat

The Company plans to initiate in the third quarter of 2016 a phase 2 study of tazemetostat in relapsed or refractory patients with mesothelioma characterized by mutations in an enzyme called BAP1, which is involved in regulating EZH2 expression.
